Realization of a new Magnetic Scanning X-ray Microscope and Investigation of Landau Structures under Pulsed Field Excitation

af Markus Weigand

Magnetic nanostructures in thin films and their behavior have seen a drastic increase in scientific interest in the last decades. Similarly, X-ray microscopy has moved into the spotlight since the turn of the century. This thesis combines both topics with the investigation of magnetic vortex structures under pulsed field excitation using both micromagnetic simulations and time resolved magnetic X-ray microscopy. This allowed the observation of vortex core polarization switches with
